The known risks of untreated psychosis can include:

The duration of untreated psychosis, or DUP, is a significant factor in the prognosis for a psychotic disorder or related condition. The more time passes between the first psychosis symptoms and adequate treatment, the poorer the prognosis. Evidence suggests that early treatment—and a shorter DUP—promotes better symptom improvement and overall functioning in everyday life.

There is yet inadequate proof to say conclusively that psychosis causes permanent brain damage. But researchers are still pursuing a better understanding of the neurological impact of psychotic episodes. And, regardless of the cause-and-effect realities involved, immediate clinical attention for symptoms of psychosis is widely recommended.
